There is so much hidden events and stuff here it's unbelievable, but here's what it looks like.
Overview:
View from Tower:
Main street:
Sewers which run under the city:
Loads more stuff hidden around the area. There's a cave where you are ambushed bu spiders, there's a crevice in the mountains where Goblins keep a grisly watch over the Town, the tower is about twice as high as it looks due to it delving deep into the ground. There's too much to mention, but I wont spoil it all :)
This area is around 80% complete.
